Does belarus require customs form royal mail

According to Royal Mail's guidelines, Belarus is one of the countries that requires a customs form to be completed for international mail items.

Here are the details:

Royal Mail provides a free customs form (CN23) that can be downloaded from their website or obtained from a post office. You can also use a commercial invoice or a proforma invoice as an alternative to the customs form, but this must be accompanied by a commercial invoice or a proforma invoice that meets the requirements of the Belarusian customs authorities.

It's worth noting that failure to complete the customs form correctly or provide the required information may result in delays or even refusal of delivery by the Belarusian customs authorities.

If you're unsure about the requirements for sending mail to Belarus, I recommend checking with Royal Mail or the Belarusian postal service (Belposhta) for the most up-to-date information.
